AUTOMATIC STOP MECHANISM.

Specification of Letters Patent.

Patented Jan. 25, 1916.

Original application filed. March 10, 1913, Serial No. 753,362. Divided and this application filed July 14,

To all whom it may concern Be it known that I, EDWARD R. KAsr, a citizen of the United States of America, and a resident of Pearl River, New York, have invented a new and useful Improvement in Automatic Stop Mechanism, which invention is fully set forth in the following specification.

T he present invention is an improvement in automatic stop-mechanism, and this application is a division of my application, Serial No. 753,362, filed March 10, 1913.

One of the objects of the invention is to provide a simple and efficient mechanism for automatically stopping the machine to which it is applied, at a predetermined time or upon the happening of certain contingencies.

The invention will be better understood bv reference to the accompanying drawing, illustrating one embodiment of the inventive idea, and wherein- Figure 1 is a view in elevation of a part of an insetting machine to which the invention is applied; and Fig. 2 is a perspective view of the main features of the invention.

Referring to the drawing, wherein like reference numerals indicate like parts, 10 is a pulley mounted on a shaft 11 carried in standards 12 and 18, a belt 14 engaging the said pulley and rotating the same. The power from the pulley is transmitted through a pinion 15 carried by shaft 11 through a gear 16 mounted on a shaft 17, from which shaft the various parts of the machine may be driven.

A movable element or clutch 18 is interposed between pinion 15 and pulley 10, and means are provided for manually and automatically moving said element or opening said clutch to stop the machine. The machine may be manually stopped through a handle 19 pivoted at 20 to the frame of the machine, said handle being connected to a link 21, one end of which is secured to an arm 22 pivoted on shaft 23. Secured to this shaft is a second arm 24 to which is con nected one end of a link 25, the other end of said link being connected to one arm 26 of a bell-crank lever pivoted at 27, the other arm 28 of said lever having a forked engagement with clutch member 18.

In my Patent 1,039,541, dated September Serial No. 38,811.

24, 1912, I have described and claimed an improved form of calipering device, which employs a signal 29 pivoted on a shaft 30, which shaft is rotated upon the passage of a defective signature. I have herein provided means for automatically operating the movable element or opening the clutch 18 upon the rotation of shaft 30. Secured to said shaft is an arm 31 provided with a pin 32, which is engaged by the hooked end of an arm 33, the other end of said arm being connected to the upper extremity of one arm 34 of a bell-crank lever pivoted at 35, the other arm 38 of said lever being provided with a small cam plate 37. Keyed to a vertical shaft 38, which is driven from shaft 17 through any suitable connections, as for example bevel gearing (not shown), is a collar 39 to which is secured an arm 40 in the end of which a pin 41 is vertically movable. Normally this pin 41 is in the position indicated in Fig. 2, and when the shaft 30 is rocked under the influence of the calipering device, plate 37 engages pin 41 and depresses the same into the position shown in Fig. 1. Secured to link 21 is a finger 42, and when said pin 41 is in its lowermost position, upon the continued r0- tation of shaft 38 it engages the said finger 42 and moves link 21 to the right, thereby opening the clutch and stopping the machine. Finger 42 is provided with a cam surface 43, which lies in the path of the pin 41 and acts to return it to the position shown in Fig. 2, after link 21 has been moved to open the clutch. I

lVhile for the purpose of illustration, the improved automatic stop mechan sm has been shown 'as applied to an insetting machine, it will be obvious that the invention has a broad application and that the device may be used on practically all machines which it is desired to automatically stop, either by opening a clutch, closing or opening an electric circuit. or otherwise.

As will be apparent, the invention is susceptible of a variety of embodiments conforming to the definition ofthe invent-ion gi en in the c aims which follow.

What is claimed is 1. In a device of the character described, the combination of a clutch, mechanism for automatically operating the same including a normally stationary member, a second member rotatable above the first but normally out of engagement therewith, and nonrotating means normally out of engagement with the second member and ope 'able to move the said member into engagement with the first member, whereby the latter participates in the movement of the former to operate the clutch. V

2'. In a device of the character described, the combination of a clutch, mechanism for automatically operating the same including a normally stationary member, a second member rotatable above the first but normally out of engagementtherewith, a pin carried by said second member, and nonrotating means normally out of engagement with said pin and operable to move the pin into position to engage said first member, whereby the latter participates in the movement'of the former to operate the clutch.

3. In a device of the character described, the combination of a clutch, mechanism for automatically operating the same, including a normally stationary member, a second member rotatable above the first but normally out of engagement therewith, a pin carried by said second member, means moving said pin into position to engage said first member, whereby the latter participates in the movement of the former to operate the clutch, and a cam engaging said pin and returning it to its original position.

4. In a device of the character described,

the combination of a clutch, mechanism for automatically operating the same including a normally stationary member, a second member rotatable above the first but normally out of engagement therewith, a vertically movable pin carried by said second member, means engaging the upper end of'said pin and moving the same into position to engage said first member, said first member being provided with a cam surface that engages the lower end of said pin and returns.

it to its original position.

, 5. In combination, a movable element, mechanism for automatically operatlngthe same including a normally stationary member, a second member rotatable above the first but normally out of engagement therewith, and non-rotating means normally out of engagement with the second member and operable to move the said member intoengagement With'the first member, whereby and non-rotating means normally out of engagement with said pin and operable to move the pin into position to engage said first member, whereby the latter participates in the movementof the former to operate the movable element.

' 7. In combination, a movable element,

mechanism for automatically operating the same including a normally stationary member, a second member rotatable above the.

first, but normally out of engagement therewith, a pin carried by said second member, means movin said pm into posltion to engage said member, whereby the latter participates in the movement of the ,former to operate the movable element, and a cam engaging said pin and returning it to its original position.

8. In combination, a movable element, mechanism for automatically operating the same including a normally stationary member, a second member rotatable above the first but normally out of engagement therewith, a vertically 'movable pin carried by said second member, means engaging the upper end of said pin and moving the same into position to engage said first member, said first member being provided with a cam surface that engages the lower end of said pin and returns it to its original position.

mechanism for automatically operating the same including a normally stationary member, a second member rotatable above the first but normally out of engagement therewith, and a cam normally. out of the path of the second member but movable into the said 9. In combination, a movable element,
